在Java中使用不同的返回类型进行重载？ [英] Overload with different return type in Java?

问题描述

为什么仅通过更改返回类型来重载函数是不可能的？这将在未来的Java版本中发生变化吗？

Why is it not possible to overload a function just by changing the return type? Will that change in a future version of Java?

顺便说一句，仅供参考，这可能在C ++中实现吗？

By the way, just for reference, is this possible in C++?

推荐答案

你不能用Java做，也不能用C ++做。理由是单独的返回值不足以让编译器找出要调用的函数：

You can't do it in Java, and you can't do it in C++. The rationale is that the return value alone is not sufficient for the compiler to figure out which function to call:

public int foo() {...}
public float foo() {..}

...
foo(); // which one?
